# 4475 Binding TRadioButton Instances to Boolean TDataSet Columns Results in Runtime Error

---

In a Group Panel I have 2 radio buttons () Yes () No.

()No ValueSelected = False and that works fine. However, () Yes ValueSelected = True and the following error occurs when the radio button is clicked:

Uncaught error: 'Invalid literal boolean '0' specified.'

Note, it works for the () No. And, I know a checkbox can do a Y/N, but this is a required field and is being changed from a checkbox as users are required to explicitly state a Yes or a No hence the radio buttons.
